Hey this isnt really a tuning question but it has to do with hptuners.

I am getting ready to buy hptuners off of a friend. He has the professional version yadda yadda it has everything he says. How much should it be worth, used?

Can the 2.0 ss/sc cobalts use the professional version, can they use the hardware or whatever that it comes with. What are the pros to having the professional version vs the standard version of hptuners.

Thanks for your time guys.

nothing against HPT but buy EFI Live! I mean if u know alot about tuning I would buy EFI Live theres so much more EFI can do over HPT!
